I needed a LightwaveRF remote switch to control outside lights on my porch and driveway. I have one CFL and two LED bulbs out there. Total load = 15W.

The standard LightwaveRF switch replacement LightwaveRF 2 Year Guarantee 1 Gang 2 Way Dimmer 250W Stainless Steel won't do here, because it needs to see a proper resistive load between itself and Neutral to keep itself powered. That's the way they designed them - One of the side-effects of UK lighting circuits rarely having a Neutral connection at the switch box, I'm afraid.

I digress. This inline relay solves the problem perfectly. It would normally fit inside a single gang, 47mm deep back box but unfortunately, I've got a 3-gang switch on there, with a big bundle of wires taking up all the space behind.

Instead, I have the inline relay inside a stud wall, sitting on top of a nogging. I dropped it in there by pulling the plastic back box partially out of the wall. Wires from the relay come into the bottom of the back box. I have the relay supplying power to the 'common' of two of the switches. These two wall switches then act as 'enables' for the two sets of lights outside, although I could have dispensed with the manual switches altogether. I do have a permanent Live and Neutral connection in my back box, so the inline relay was made for the job.

My WiFi Link controls the relay from about 30 feet away, through 3 or 4 walls. Another cool feature - the unit has an integral fuse holder with a 5A fuse, to protect itself.

The user guide doesn't show dimensions. The unit is a LOT smaller than I anticipated, so I've supplied a photo.

These are small and work exactly as hoped. The only downside really (and this is a lightwave issue generally) is that you need to physically access the relay every time that you want to pair it with a controller. It would be more more convenient if you could initiate the pairing from a (previously paired) smartphone for example.

Works well in an old house with thick walls and I get about a 25M range (I can operate the light in my office from the end of my garden).

The unit has two relays (one for each output) and the default state after installation (or a power-cut) is for both relays to be off. In this state neither of the outputs will be connected to the common terminal. You have to send a command to the unit for one of the relays to be turned on.

There is always a short delay (approx. 1 second) before a command turns on the appropriate relay. Basically when you send a command the currently 'on' relay will turn off immediately and then there is a slight pause before the other one is turned on. This is ideal for something like a garage door, but can be disconcerting when you turn on a light in the middle of the night and nothing happens for a second or so.

These really do the job. Small and easy to fit, I use them for electric blinds (they can stop the blind as well as raise and lower) as they are so much cheaper and neater than those 'recommended' for these. Also useful for lighting (Lightwave do not do a 'mixed' wireless and wired switch, so use this to make it all wireless - will fit into a backbox behind a wireless switch), integrating garage doors into the Lightwave system (forget plippers that can get lost, just use your phone) or isolating equipment kids may fiddle with.

I'm no electrician so the documentation was a little sparse for me. It seems to be written with the experienced professional in mind. Could do with some specific examples of how to wire certain appliances.

That said, it's compact, seems well made and works a treat. It will fit snugly inside a standard back box with a blanking plate on. I had to ask for dimensions from Lightwave, as they don't quote them anywhere (H52mm x W52mm x D26mm).

This little unit is a good idea. I'm an electrician and have used these wifi relays as makes it possible for people to have lights installed without the mess and disturbance of installing additional cable to a wall mounted switch, as the switches can be battery operated. I have installed about 10 of these in the past, and only had to replace one of them that had been used about 18 months.

This solved a difficult problem for us. Its beast to set up and works well. I use it with a time switch, so if I've found that if i rely on that to switch the appliance off rather than switching it off with the remote, I need to switch it off before pressing the on button, to reset it.

Used to switch on and off a pair of front door LED lanterns - either side of the front door.
Hence, can control c/o the LightwaveRF system.

Fitted the relay within a single Marshall Tufflex surface mount Socket.

My also stick on a Lightwave PIR near the front door ( and pair up with the relay) so the lights can be controlled by both the PIR and the LightwaveRF system.
